Types Of Poles
Types of poles
They can be divided into three types namely; Tangent distribution poles, guyed distribution poles, and self-supporting distribution poles.
Which type of poles are commonly used for distribution?
Wooden poles, steel poles, RCC and PCC poles are used for distribution purpose and steel towers are used for transmission purpose. Wooden poles: Wooden poles are used for temporary electrical line. The length of wooden pole is kept 6-9 meters out of which 1-2 meter length buried in the ground.
What are the poles in electrical?
A utility pole is a column or post typically made out of wood used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and street lights.
What is the height of HT pole?
Transmission line poles or structures are commonly between 60 and 140 feet tall. Distribution line structures are approximately 40 to 60 feet tall.
What is the height of 11kv pole?
| Pole Material | Iron |
|---|---|
| Pole Height | 15-20 Feet |
| Surface Finish | Coated |
| Width | 3-5 Feet |
What is RCC poles?
The RCC Fencing Pole which we supply is developed by the use of extremely strong concrete material. These poles are accurate in shape and thickness and ensure the perfect functioning for longer years.
What is PSC pole?
Pre-Stressed Cement Concrete Poles PSC / PCC poles are cement concrete poles which are pre-stressed using steel wires to provide more structural strength.
What are large power poles called?
A transmission tower, also known as an electricity pylon or simply a pylon in British English and as a hydro tower in Canadian English, is a tall structure, usually a steel lattice tower, used to support an overhead power line.
Which types of poles are more preferred and why?
The reinforced cement concrete poles have greater mechanical strength, longer life and permit longer spans (80 to 200 meters) than steel poles. These poles also give a good outlook, require little maintenance and possess better insulating properties. Therefore, these poles have become very popular in recent years.
What is a 3-pole switch?
Three pole or three-way switches are used to control one or more lights or fixtures from multiple locations, such as the top and bottom of a flight of stairs. Single pole and three pole switches look the same when installed but are used for different purposes.
What are the 3 power lines?
Telephone and cable wires are typically the lowest wires. Transformers convert higher voltage electricity carried by primary wires and lowers the voltage for use by customers. Guy wires help stabilize utility poles. A ground wire runs the entire length of the pole.
What is the height of 33kv pole?
It considers a three-phase stout class wood pole overhead distribution line, having a pole height of 9m and an average span length of 90m. For the structure, a 2.5m steel crossarm, a 0.75m crossarm strut and an 80mm insulator bracket (only for the central phase insulator) are used.
What is pole distance?
Definition of distance pole : the pole that indicates the distance on a racecourse.
What is the current in 11kv line?
An 11 kV distribution circuit may carry 150 A in each of its three phases, thus transmitting a power of 3 MW.
Which conductor is used in 11kv line?
Estimate for 11 KV HT Line (161.23 Kms.) with ACSR Conductor 80mm2 with span 40 meters and double earth wire with guards (System Strengthening -161.23 Kms.)
What is a 33kV line?
The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.
What is the size of 33kV cable?
Tender Item: 33 KV Armoured Aluminium XLPE Cable for having sizes 3C x 185 sq. mm & 3C x 400 sq. mm.
Is 11kV high tension?
The operating voltage of high voltage cables is up to 11 kV. The High tension wire is used for the transmission of electrical energy with high voltage. These types of cables are often used for long-distance transmission.
Why do we use PCC?
The objective of plain cement concrete alias PCC is to arrange a firm impermeable bed to RCC in the foundation where the soil is soft and flexible. It is mostly applied over brick flat soling or devoid of brick flat soling. It is also known as Cement Concrete (CC) or Blinding Concrete.
What is RCC full form?
The full form of RCC is Reinforced Cement Concrete, a composite material made from concrete and steel reinforcement.
